A sea current generator aquarium including an air fight water chamber located at one end of the aquarium with a first opening into the aquarium extending across the bottom of the chamber. At the opposite end of the aquarium between the end wall and a horizontal divider wall is a second opening into an upper chamber which is open to atmosphere. A constant flow air pump is connected to the water chamber for pumping air in and expelling water out of the first opening into the aquarium and then into the upper chamber. An air valve which cycles open or closed, connects the water chamber to atmosphere and in its vented position, the valve dumps the capacity of the pump and allows the elevated water column in the aquarium and upper chamber to move back into the water chamber through both openings until the valve cycles closed thereby creating a back and forth current of water within the bottom regions of the aquarium.
